Which biome is characterized by constant temperatures and high rainfall?

The tropical rain forest biome is characterized by a consistently warm climate with minimal temperature variation throughout the year, typically averaging between 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit). This biome also experiences abundant rainfall, often exceeding 2000 millimeters (about 79 inches) annually. The combination of high temperatures and high rainfall creates an environment that supports a rich diversity of plant and animal life, making it one of the most biodiverse ecosystems on the planet. The lush vegetation, including tall trees, vines, and a variety of understory plants, thrives in these conditions, which also contribute to the layering of the forest structure, where different plants and animals occupy various levels of the canopy.

In contrast, the savanna biome has distinct wet and dry seasons, resulting in more variable temperatures and lower overall rainfall compared to tropical rain forests. The desert biome is characterized by extremely low precipitation and often high temperatures during the day with significant cooling at night, making it quite different from a tropical rain forest. The temperate deciduous forest biome experiences four distinct seasons, including colder winters and varying rainfall patterns, which also sets it apart from the constant conditions found in the tropical rain forest.
